Micro-machined membrane deformable mirrors (MMDMs) show potential for cryogenic applications. One of three tested mirrors maintained sufficient quality for wavefront correction at 78K, though deflection decreased 20%.

Area of Science:

Optical Engineering
Cryogenic Technology
Adaptive Optics

Background:

Micro-machined membrane deformable mirrors (MMDMs) are critical for adaptive optics systems.
Evaluating MMDMs performance at cryogenic temperatures is essential for applications like space telescopes and advanced imaging.

Purpose of the Study:

To assess the suitability of 37-channel MMDMs for wavefront correction at cryogenic temperatures (78K).
To investigate changes in mirror figure and influence functions upon cooling.

Main Methods:

Experimental cooling of three MMDMs from OKO Technologies to 78K.
Measurement of initial mirror figure and influence functions at cryogenic temperatures.
Comparison of cryogenic performance with room temperature data and theoretical predictions.

Main Results:

One of three tested MMDMs exhibited minimal static aberrations, indicating suitability for cryogenic wavefront correction.
MMDM influence functions at 78K were similar in shape to room temperature and theoretical models.
Surface deflection magnitude at 78K was approximately 20% lower than at room temperature.

Conclusions:

MMDMs can be viable wavefront correctors at cryogenic temperatures, with careful selection of individual units.
Cooling affects the surface deflection magnitude but not significantly the shape of influence functions.
Further research can optimize MMDM design for enhanced cryogenic performance.
